YUV420 color space via Shaders

Hello,

I am trying to render a YUV420 image color space into a Texture2D object. I relied on this link from StackOverflow and I set the shader as it is. Afterward, I load the data and I try to feed the tex as

Texture2D(dimension.width, dimension.height, TextureFormat.RGB24, false);

through the

tex.LoadRawTextureData(pImage, pImageSize);

which the pImage is a pointer.

Although, I know the fact that a YUV420 image has half-size than RGB but I can't set the Texture2D with the appropriate TextureFormat.

Do you have any suggestions?
